Este archivo se encuentra en el dominio público en los Estados Unidos porque fue publicado en ese país entre los años 1929 y 1963, y, teniendo un aviso de derechos de autor, no se renovó su protección. A menos que su autor haya fallecido años antes, se mantiene bajo propiedad intelectual en los países o zonas que no aplican la regla del plazo más corto para las obras estadounidenses, como China continental (50 años p.m.a., a excepción de Hong Kong o Macao), Alemania (70), Canadá (70), Suiza (70), México (100) y otros países con reglas particulares.
